In Northern Italy, six fish nurseries were stocked for 112 days with common carp (Cyprinus carpio) and fertilized with pig manure at three different levels: 25 kg(L), 50 kg(M) and 75 kg (H) per hectare. The fishes were also served a pelletized ration. The manure (± 1.15 from 11% dry matter) was spread once a day for five days a week. The water temperature, pH, dissolved oxygen, total hardness such as CaCO3, nitrates, nitrites, ammonium, phosphates as PO4--, were monitored weekly. The treated fish survival rates were 100%, 93% and 86% for L, M, and H respectively. Their final weight averaged 470.0 ± 2.8 g (L), 407.0 ± 45.2 g (M) and 358.0 ±19.1 g (H). The manure rate applied per day/ha was 245 kg, 491 kg and 736 kg for L, M and H treatments respectively. The oxygen level indicated significant differences (P<0.05) in L (10.08 ±4.37) compared to M (7.40 ±4.79) and H treatments (7.48 ±3.18); pH was significantly (P<0.01) lower (7.61 ±0.18) in L than in the other two treatments (M: 7.74 ±0.16; H: 7.80 ±0.13). As for the other water chemical parameters, no significant difference was found. |
